This dissertation is focused on finding lower confidence limits for the reliability of systems consisting of Wei bull components when the reliability demonstration testing (RDT) is conducted with zero failures. The usual methods for the parameter...

My paper explores the unique forms of reproductive inequality experienced by poor women of color during the nineteenth and twentieth centuries. By analyzing the experiences of eight African-American women, I will illuminate their struggles and...

Inherited Bone Marrow Failure syndromes (IBMFS) are a heterogeneous class of diseases that converge on very few subjects. They are unified by a block in maturation of one or multiple blood lineages, are genetically inherited, and have an increased...

Very few topics in entrepreneurship have received as much attention as the entrepreneurial process. It consists of the discovery, evaluation and exploitation of opportunities to create future goods and services. Evaluation is at the center of this...

Cancer accounts for nearly one-quarter of deaths in the United States, exceeded only by heart diseases. Despite the development of various strategies to treat cancer, it remains one of the most deadly diseases worldwide due to the limited effects...

Nationally, there are increasing numbers of students who are at-risk for academic and/or social failure (U.S. Department of Education, 2009). In an attempt to address this trend, the 2004 reauthorization of the Individuals with Disabilities...

Evaluation and demonstration of system performance against specified requirements is an essential element of risk reduction during the design, development, and production phases of a product lifecycle. Typical demonstration testing focuses on...

Computational grids are some of the largest computer systems in existence today. Unfortunately they are also, in many cases, the least reliable. This research examines the use of redundancy with permutation as a method of improving reliability in...

The use of fiber reinforced polymer materials (composite FRP materials) to
strengthen existing concrete structures continues to expand as our current infrastructure
ages. However, one of the concerns when using FRP systems in this manner is...

Electroactive polymers (EAPs), including conducting polymers (CPs) such as polyaniline (PAn), and hydrogels are exciting areas of research in disciplines such as biomedical engineering, with the goal of creating low-cost, lightweight, non-toxic...

Hydrophilic and conductive characteristics in polymers are mutually exclusive of each other. Hydrophilic polymer properties allow absorption of water up to several magnitudes above their dry weight. However, due to their molecular structure, they...

Purpose: The initial and long term bond failure rates of two orthodontic indirect bonding methods were compared. Materials and Methods: A review of 191 bondings provided a data base of bond failures for two indirect bonding methods. One method used...

Diabetic cardiomyopathy (DCM) is a common complication leading to accelerated cardiovascular failure in diabetic patients. Even though the exact mechanism(s) behind this disease still remain unclear, research from several laboratories including our...

Early detection of human organ diseases is of great importance for the accurate diagnosis and institution of appropriate therapies. This can potentially prevent progression to end-stage disease by detecting precursors that evaluate organ...

In the electronic and microfabrication industry, die separation is one of the most critical steps in producing an undamaged, stand-alone micro-scale device. For silicon based devices, it is the predominant step governing resistance to die failure...

Modular hip implants are currently being used in total hip arthroplasty revision procedures because it is common to have little or no bone left in the proximal region of the femur and it is difficult to accurately size implants based off of...

In 1991, as democratic ideals spread through the former Soviet sphere, newly independent nations and satellite countries began engaging in the truly challenging, albeit hopeful task of dual state- and democracy-building endeavors. After twenty...
